WATER-PLUG.

SPECIFICATION forming part of Letters Patent No. 584,682, dated June 15,189'?.

Application inea February 11,1897. serial No. 622,987.- (No modem T0 allwhom it may concern,.-

Be it known that I, HARRY H. GARRIsoN, of VVilkes-Barrdn the county ofLuzerne and State of Pennsylvania, have invented certain new and usefulImprovements in Vater- Plugs; and I do hereby declare the following tobe afull, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanyingy drawings,which form part ofthis speciiication.

My invention relates to improvements in water-plugs and pertains to aplug constructed to permit an escape of the water remaining in the plugafter the inlet thereto from the water-main has been closed, as will befully described hereinafter, and particularly pointed out in the claims.

The object of my invention is to so construct a water-plug that thewater remaining therein after the inlet from the water-main is closed ispermitted to escape and pass into the sewer, whereby an antifreezingplug is produced. The particular manner by which this result isaccomplished is through the medium of a teleseoping valve so arrangedand constructed in relation to the water-main and the sewer-outlet thatthe opening of the valve will close the outlet to the sewer to preventany escape of the water therethrough and to automatically open thesewer-escape when the valve is closed to permit the escape ot' the waterremaining therein through the sewer or other waste-outlet.

In the accompanying drawings, Figure 1 is a vertical sectional view of awater-plu g which embodies my invention, the plug being shown closed.Fig. 2 is a similar view, the plug being shown open. Fig. 3 is anenlarged detail view of the sleeve and its rod for eiiecting the openingand closing of the valve.

Referring now to the drawings, A indicates the casing or outer tube ofthe plug, through which the water is communicated to the outlet thereofC, the inlet from the water-main; B, the outlet through which the wateris taken from the plug-tube A, and D the outlet situated at the lowerend of the tube A and below the water-main, said outlet havingcommunication in any suitable manner with the sewer or other wastecommunication or source.

Situated within the tube A, near its upper end, is a web a., andextendingfrom the top of the tube down to said web is a sleeve 13, whichsleeve is internally screwthreaded, as clearly shown in Fig. 3. lengthequal to the travel of the rod 12, which has its upper end passingthrough said web and into the sleeve, the rod being externallyscrew-threaded to engage the internal screwthreads of the sleeve. Thisrod has its lower end connected to a tubular valve 2 within the tube A,the tube and the valve having lateral seating portions r at the upperend of the valve and just above the inlet, and also the seating portionss at the lower end of the valve and just below the said inlet, toprevent any escape of water between the valve and the tube when thevalve is closed, as shown in Fig. 1, the valve extending across theinlet-opening, as shown. Projecting from the lower end of the plug is anextension 7, adapted to pass within the tube 8.

Above the lower end of the valve 2 (which is in the form of an invertedcup) are provided the opening or openings 5 and 6, and situated in theupper end of the valve .are the opening or openings 3 and 4, which areadapted to be closed by engagement with the upper end of the extension 7when the valve is lowered. the inlet, the openings 3 andaare opened bymoving out of engagement with said extension 7. i

The sleeve or tube 13 is supported in amanner to prevent any verticalmovement thereof, but is free to turn. Owing to this construction, itwill be seen that when the sleeve is turned the rod will be raised orlowered (according to the direction in which the sleeve is rotated) andconsequently the rod correspondingly moved.

The operation is as follows: As illustrated in Fig. 1, the plug isclosed and the water remaining therein is permitted a free escapethrough the valves or openings 3 and 4, the passage-ways or openings 5and G of the depending tube S, and the space 9 to the sewer or otherwaste-escape. When the plug is opened, as shown in Fig. 2, by thelowering of the valve 2, the openings 5 and G are closed, s0 that noescape will be permitted to the sewer.

It will be noted that the passage-ways 5 and 6 in the lower end of thetube projecting from The said sleeve is of a When the valve 2 is raisedfor opening ICO the interior of the valve 2 are so situated that thevalve has passed up and entirely closed the water-main inlet before thepassages have reached the upper end of the tube 7. This constructionprevents absolutely any escape of water to the sewer until thewater-main inlet has been entirely closed.

While I have shown the tube S provided with the openings 5 and 6, itwill be readily understood that the saine result will be aecomplished bymaking the tube 8 sufiiciently short to be above the upper end of thetube 7 when the valve is closed, which, as will be readily understood,will permit an escape of the water remaining in the plug. Also I desireit noted that while I show the extension 7 adapted to close the openings3 and 4 at the upper end of the valve this is not absolutely necessary,provided the tube 8 and the extension iit tight enough to prevent anyescape of waterbetween them. By having said open'- ings closed by theextension, however, the tube and extension need not fit so tightly.

While I here show and describe a sleeve for operating` the rod, I desireto state that other means may be used for elevating the rod without inany manneraffectin g the other portion of my invention. The sleeve whenused may be operated directly or through the medium of a key, asdesired.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination of a casing having inlet and outlet openings, acup-shaped valve fitting within said casing and extending across saidinlet-opening when raised, a wasteescape at the lower end of the casing,said valve having an escape-opening in communication with saidwaste-escape through said valve, substantially as described.

2. A water-plug comprising a casin g having an inlet and an outletopening, the lower end of the casing bein g enlarged, a cup-shaped valveiitting within said casing and extending across said inlet when raised,and below it when lowered, valve-seats above and below said inlet, thesaid valve having an enlarged lower end fitting the enlargement of thecasing and the scat formed by the upper 5o end of the enlargement, andthe upper end oi the valve having a seat above the said inlet-opening,substantially as described.

A water-plug comprising a casing having inlet and outlet openings, acup-shaped valve fitting within said casing and extending across saidopening when raised, a tube carried by and within said valve, the tubehaving an open lower end and escape-openings in its upper end, aprojection extending from the bottom of the casing and tting within saidtube, the tube having openings in communication with the valve whenraised, whereby the projection is adapted to close both openings in saidtube when the valve is lowered to open the inlet, and the casing havingan outlet at its lower end, substantially as described.

4. A water-plug comprising a casing having inlet and outlet openings, acup-shaped valve iittin g within the casing and extending across theinlet when raised, the casing having an escape-opening at its lower end,a tube depending from the inner side of the top of the valve and havingopenings in its top and side walls, and an extension carried by thecasing extending up and telescoping said tube for closing the openingstherein when the valve is lowered, substantially as described.

5. A water-plug comprising a casing having inlet and outlet openings, avalve fitting therein and adaped to extend across and close saidinlet-opening when raised, the lower end of the casing having awaste-opening, the valve having an escape-opening in communication withthe waste-opening through said valve, and an extension projecting upwardfrom said casing and adapted to close the valve-'escape when the saineis lowered, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
